轮播上的响应式卡片叠加

Question

我在轮播之上制作了一个登录/注册卡。但是我的利润是硬编码的，一切似乎都很复杂。它在台式机上看起来不错，但在手机/平板电脑上却没有响应。我是webdev的新手，刚刚学习了大约两个星期，所以请原谅我缺乏的知识。

这是我的html代码：

<div id="carouselFinal" class="carousel slide" data-ride="carousel" data-interval="3000" data-pause="false">

  <div class="carousel-inner">
    <div class=" carousel-item active">
      <img class="d-block w-100" src="./../assets/images1.jpg" alt="First slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="./../assets/images2.jpg" alt="Second slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="./../assets/images3.jpg" alt="Second slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="./../assets/images4.jpg" alt="Second slide">
    </div>
    <div class="carousel-item">

    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="./../assets/images6.jpg" alt="Third slide">
    </div>
    <div class="carousel-item">

    </div>
    <div class="carousel-item">

我该如何做出响应？这段代码的行为很奇怪。

我已经将它部署在Firebase上：https://shopping-cart-client-23081997.web.app/，如果您想查看的话。

谢谢！

Answer 1

它在台式机上看起来不错，但在手机或平板电脑上却没有响应，因为它没有响应。要使您的网站具有响应能力，应该从头开始，因此，相对度量（％）的使用不是您所使用的绝对度量（px）的使用。之后，如果有必要，因此如果在某些断点处看起来仍然不好，则可以使用媒体查询为所有内容添加香料。从概念化到站点设计，所有响应都应正确考虑。
